To all whom it may concern: v

Be it known that I, ENOCH HENRY EATON,

a citizen'of the United States of America, and a resident of Moulton, in the county of Appanoose and State of Iowa, have invented a neitY and useful Rotary. Enginejof which the fol-- lowing is a specification.

The obfeet of vthis invention is to provide improved means for 1utilizing the expansive force of steam for the propulsion ofmech- My yinvention consists in the. construction, arrangement,l and combination of i elements hereinafter set forth, 'pointed out in my claim,-

and illustrated bythe accompanying drawlllgs, in wliiul1- Figure lis a sectional elevation of my en` gine, longitudinally in the main shaft. Fig.' 2 is a transverse sectional elevationon the line l 1 of Fig. 1. Fig. 3 is an elevation of the camovheel detached from the engine.

In the construction of the engine as shown the numeral 10..designates the main shaft,

mounted forrotation in bearings 11 l2, formed in or fixed to the sides 13 14 of theenginc- -casing. The sides 13 14 of the casing'are circular, and a rim 15 is mounted on the peripheries thereof and secured thereto. The inner or adjacent faces of the sides 13 14 of the casing are plane and equidistant at all points from each other, being parallel and of the same thickness. Mounted rigidly on the same shaft 10 is a piston-head 1G of cylindrieal form and of less diameter than the inner diameter of the casing, thus formingr an annular steam-chamber vbetween the periphery of the piston and the axial face of the casing-rim 15, which steam-chamber is traversed radially of the main shaft by a wing;` or head 17, fixed to the piston 16 and projecting from the periphery' thereof. The vouter ,end of the wing or head 17 engages with and travels in contact on thc axial face of the rimy in advance of the aperture 1D of the rim 15..

15 of the casing.

The rim 15 of the casing is mounted 011 and ixcd to a suitable base or support 18. rlhe rim i5 is aperturcd at 19 in one portion, and a gate ZO is mounted for reciproeatiou in said aperture and in slide bearings or grooves 21 22, formcdin the inner faces of the sides 13 14. 'A stem 23 is fixed to and extends from the outer end of the gate 2O and is loosely connected at its outer endto the inner bifureated end portion of a lever 24. The-.lever 24 is fulerumed near its center on a pin-25,` seated in ears 26 27, formed ou .a steam-chest!V 28, andfthe outer end of the lever is con-1 4 neeted witha pitman 29. kvertically positioned-between guides 80 and The pitman 29 isy 31, fixed to the side 13 of the easing, and a pin 32 is Vseated in and transversely ofthe lower @ne of sind pinnen. -A head 33 is. formed von the end of the pin- 32, and an antifriction-,sleeve 34 is mounted loosely on said pin between the head 33 and the pitman 29.

,Anvhcel or disk 35 is mounted rigidly on they `main-shaft pin atsome little distance from the side 18 of the casing, and said wheel is pro'- vided with a eanrgroove in the face thereof adjacent to said casing. The groove 36 is roamed out, cut under,` or dovetailed'in crossscction to receive and retain in its inner por- 'tion the head 33 on the pitmanpin. The

groove 36 is annular throughout a major p0rtiou of its length andis depressed at one point abruptly toward the main point or axis of the wheel to forma rentrant portion 3G,-wl1ieh is of greater width than the major portion of the groove to permit insertion and removal of the head "of a valve-stem 41.

On the opposite side of the steamlcasingl from the wheel 35 there isloeated an eccentric disk 37, connected by the usual strap 38 to a pitnian 39, the eccentric disk being rigidly mounted on the main shaft 10. rlhe upper end of the pitman 39 lis connected to the extremity of the horizontal arm of the bell.- crank lever 10,.whieh bell-crank is fulcrumed on the steam-chest 28 and has the extremityof its vertical arm pivoted to the outer end mounted :on the inner end of the stem 41 for .9o A slide-valve 42 is reciproeation within the steam-chest and controls an ingress-port 43 to' the steamjchamber steam is admitted to the chest' 28 th rougll'the- IOC) supply-pipe 45, vis governed in its admission to thecylinder by the slide-valve 42,'enters the cylinder between the wing or head 17 and the gateor valve 20, and expanding therein forces the Wing or head 17 in a rotary path around the interior of the rim l5, and since the head 17 is connected rigidlywith the disk 16 and main shaft it follows that the travel of the head will cause the rotation of the shaft and mechanism connected thereto., In the rotation of the shaft l the Wheel is 1o tated and the ca1n-gr0ove therein operates the pitman 29 and lever 2lto raise and lower the valve-stem and valve 20 at such times in relation to the rotation of the disklG as is necessary to permit the passage of the iving or head 17 beyond the gate orvalve 20. 1 In the rotation of the shal t the eccentric 37 is rotated and, acting through the strap 2S, pitnian 39, and bell-crank lever At0, reciprocates theslide-valve 4:2 and cuts the steam on or olf, as is desirable to control the admission of the steam at the proper time to the space in front of the valve 20. and at the rear of the wing or head 17.

I claim as my inventionv A rotary engine comprising the following elements in combination, to wit: a casing having ingress and egress portsyaconcentric piston `mounted within said casing; a

gate 20 mounted for reciprocation trans` vcrsely of the casing; a lever mounted for oscillation; a stem connecting one end of the Y lever with the gate 20;\a pitinan connected `to the other aendl of the lever; guides mounted on the casingand laterally extended therefrom to receiveand guide the pitman; a pin laterally extended from the lower end of the pitman and provided with a beveled head 33; aginain shaft carrying the concentric piston; a wheel mounted'on` the main shaft and pro` vided with a cam-groove in its face adjacent to the easing,iwhich cam-groove is reamed out and undercut to receive the beveled head 33 and widened at the rentrant portion thereof to permit removal and insertion of said'head therein; a steam-chestmounted on the cas,-

ing; a slide-valve in said steaimchest controlling the ingress-ports to the casing;` a hell-crank lever mounted on the casing and connecting at one end to the slide-valve; `an eccentric connected to the other end of the bell-crank lever; an eccentric wheel or disk mounted on the main shaft and connected with the eccentric; and a power-.wheel mounted on the main shaft.
